如何从Microsoft Office 2007保存ImageMSO图标?

标签: vba icons office-2007

我从Microsoft Office 2007中发现了许多漂亮的图标。你对提取物有什么想法吗?使用VBA将所有图标保存为PNG文件?

Partial ImageMSO http://rabu4g.bay.livefilestore.com/y1p2SF1q63YjDjPNmK4nYMW2644r9AO2aAsE__vBYznTeXD0b4SJUU0O07fxPD0r7aO_83gCJ-8OfcOQsFKG0fQMRnTEneBU1TI/Capture.PNG

以下代码是用于从ImageMSO获取图像的代码。

Application.CommandBars.GetImageMso([name], [width], [height])

我可以将所有内容显示为PictureBox控件并将excel文件另存为网页。但是,每个图标质量都很低。

此外,我尝试使用以下代码创建用于导出为Bitmap对象的C#Excel加载项项目。但我发现它无法导出为半透明的PNG。

stdole.IPictureDisp p = Application.CommandBars.GetImageMso(fileName, size, size);
Bitmap b = Bitmap.FromHbitmap((IntPtr)p.Handle, (IntPtr)p.hPal);

PS。我想将所有图标保存为PNG格式,因为我需要使用它的半透明功能。它允许我使用大多数背景颜色的所有图标而不是白色背景。

我在Excel开发中经常使用ImageMso。偶然发现了这篇文章后,我更进了一步,将一个包放在一起,以视觉方式搜索,提取并保存Microsoft Excel中的图标作为文件,或者复制并粘贴(具有alpha通道透明度)到另一个应用程序。我还从各种来源编制了一个包含8,899个不同ImageMso名称的列表。我希望其他人能发现这个有用。

我已经完成了一个C#Utility类,用于将Office2007图库图标提取到.png文件,同时保持其透明度。主要代码取自Andrew Whitechapel撰写的一篇精彩文章( http://blogs.msdn.com/b/andreww/archive/2007/10/10/preserving-the-alpha-channel-when-converting-images.aspx)。我已将其与Office 2007示例图标表集成,以防您想要将所有这些图标提取到目标文件夹。

步骤是:

1)在http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=11675

下载Office Gallery电子表格

2)使用Office2007IconsGallery.xlsm示例电子表格的位置以及要提取图标的目标文件夹调用OfficeIcons.ExtractAllIcons()。

可以找到所有PNG文件here这些文件都已经是PNG格式。好编程! (一个不错的ZIP存档也可用Here)ZIP存档包含所有17个Excel图标。

使用GetImageMso方法时,最终会得到对象的IPicture接口。 IPicture界面访问适合以原始格式保存到文件的图标 - .ICO,.WMF或.BMP不支持PNG格式。以下链接解释了为什么这不可能直接实现:

然而,使用更复杂的方法将产生您想要的结果:

我已经尝试过Ismail的答案,但确实很有效。然而,我花了一段时间才弄清楚如何使它工作。我可能会分享这些知识:

解决方案需要来自codeplex的ExcelDna:link

当我使用Net 4.0时,我没有 .zip 支持,所以我首先将 .xslm 文件解压缩到平面目录结构然后我更改了代码直接从文件中读取。 然后在Excel中我将ExcelDna扩展方法称为

=ExtractIcons("Office2207IconsGallery";"folder_where_to_store_icons")

实用程序类的using语句(对我来说):

using System.Xml.Linq;

using System.IO;

using System.Drawing;

using System.Runtime.InteropServices;

using System.Drawing.Imaging;

using Application = Microsoft.Office.Interop.Excel.Application;

using ExcelDna.Integration;

using stdole;

希望这会有所帮助....谢谢Ismail!
